We would like to upgrade an old version of Store Locator Plus, and Store Pages, to the latest versions. We MAY have customized the CSS on the old version, but I’m not sure where we would have done so. I have a daily backup of the site, so getting to those changes later if necessary shouldn’t be a problem.

However, I’m wonder if I can just deactivate SLP 3 and install the new version without damaging that SLP 3 installation. Then, if something is drastically different or I need to do some repairs, I can deactivate SLP 4 and re-active SLP 3 for a limited time.

On top of that, I need to ensure our 1800+ locations and related Store Pages are preserved.
